Hermann Henning Karl Robert von Tresckow (January 10, 1901 – July 21, 1944) was an officer in the German Army who helped organize German resistance against Adolf Hitler. He attempted to assassinate Hitler in March 1943 and drafted the Valkyrie plan for a coup against the German government. He was described by the Gestapo as the "prime mover" and the "evil spirit" behind the July 20 plot to assassinate Hitler. He committed suicide on the Eastern Front upon the plot's failure.
